If the version of the Junos OS running on the T640 router is earlier than Release 7.0, you
must upgrade the software before connecting it to the TX Matrix router. For information
about installing and upgrading Junos OS, see the Junos OS System Configuration Guide.
After you have upgraded the software on the router and are satisfied that the new
packages are successfully installed and running, issue the
command to back up the new software. For more information, see the Junos OS System
Basics and Services Command Reference.
If you are integrating an operational T640 router with the TX Matrix router, the TX Matrix
router and T640 router must each contain two host subsystems, and all host subsystems
must be running the same Junos OS release. This is a requirement for graceful switchover,
which is a requirement for integrating an operational T640 router with the TX Matrix
router. For information about graceful switchover, see the Junos OS System Basics and
Services Command Reference.
NOTE: We recommend that you run the same Junos OS release on the master
and backup Routing Engines. If you elect to run different Junos OS releases
on the Routing Engines, a change in Routing Engine mastership can cause
one or all T640 routers to be logically disconnected from the TX Matrix router.
For more information, see "Running Different Junos OS Releases on the
Routing Engines" on page 145.

Before integrating the T640 router with the TX Matrix router, you might have to upgrade
the firmware on one or more FPCs in the T640 router. To upgrade the firmware, you must
contact your customer support representative.
To determine if you need to upgrade the FPC firmware, display the version of the firmware
on all FPCs by issuing the
